Left Bundle Dranch Blockade and Atrial Fibrillation

Student Name: Professor: Subject: Date: Left Bundle Branch Blockade and Atrial Fibrillation: A case study Introduction Older adults are more vulnerable to experience postoperative complications like cardiovascular, pulmonary, and neurologic aberrations due to the effects of aging on the physiological capabilities of their body systems…

Introduction

As a matter of fact, cardiac rhythm irregularities appear even on non cardiac surgeries caused by the overall injury and trauma. Homeostatic balance can be more difficult and challenging to manage in this particular age group. In this paper, a case study of an older patient diagnosed with Left Bundle Branch Block (LBBB) and fast Atrial Fibrillation (AF) after a Total Knee Replacement (TKR) will be discussed, including the assessment, pathophysiology, treatment and management. Atrial fibrillation (AF) may result after a Total Knee Replacement (TKR) especially in older adults as a consequence of hypercoagulability and proinflammatory states associated with anaesthesia and surgical trauma, hyperadrenergic state related to perioperative stress, hypoxia, and hypovolemia leading to increased myocardial oxygen demand. Specifically, tachycardia as the heart’s compensatory mechanism to supply the systemic circulation leads to subsequent arrhythmias. In addition to AF, Left Bundle Branch Block (LBBB) also occurs as an associated condition in older adults above 75 years old due to vascular incompetency and stasis. ...

Recommendations in guideline for the device based therapy of cardiac rhythm abnormality has proved to be beneficial for reducing the risk of sudden cardiac death and has improved quality of life. However, multi-centric clinical trials are needed to find an optimal timing for the implant for an indication. Guidelines for device based therapy of cardiac rhythm abnormalities.

Once the skin succumbs to bacteria or sustains injuries from friction and shear, healing takes longer because reduced flow of blood brings nutrients and removes wastes more slowly. Ischemia due to unrelieved pressure is usually observed in the elderly, malnourished patients, patients reduced to immobility because of their medical condition, fecal incontinence, and patients under less than…

These hospitals not only keep their facilities and equipment clean and sterile but they also follow certain procedures or protocol that ensures that there are no further complications or infections for the patient. One such infection-control procedure or protocol is the Central line bundle. This particular protocol was created in order to help prevent or control central-line…

This leads to enhanced impedance to left ventricular ejection, an elevated systolic arterial pressure, and consequent interstitial fibrosis and left ventricular hypertrophy. Also, an aging person experiences a decline in the proportion of myocardial relaxation. The left ventricle takes a long time to relax, becomes stiffer, and also takes a longer time to fill in diastole. This enhances the…
